PUMP.

SPECIFICATION forming part of Letters Patent No. 448,282, dated March 17, 1891. Application filed August 6, 1890- Serial No. 361,212. (No model.)

To aZZ whom it may concern: I

Be it known that I, ABRAHAM H. Tlros, a citizen of the United States, residing at Darnall, in the county of Keya Pahaand State of Nebraska, have invented certain new and useful Improvementsin Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to improvements in pumps; and it has for its object to provide a double-acting lift or force pump, whereby a greater amount of water is drawn or forced out, all as will be hereinafter more particularly pointed out.

The annexed drawings, to which reference is made, fully illustrate my invention, in which Figure 1 represents a side view of my improved pump, partly in section. Fig. 2 is a sectional view of the cap, and Fig. Sis aplan View of the same. Fig. at is a detail view of the valve enlarged.

Referring by letter to the accompanying drawings, Adesignates the pump, and ais the stock or tube, at the lower end of which is an enlarged cylinder b, in which the plunger 0 of the piston-rod cl has its vertical play. Connected to this cylinder is a cylinder c, which communicates with the cylinder b, as at f, and above the plungers. YVithin this cylinder c is a plunger g. The rod h thereof is passed through a cap c, having a packing and connected to the lower end of a rod 9 by a joint connection It. This rod 72. passes through a guide-bar Z, secured to the pipe or tubing and serves to guide said rod in its vertical movement.

B represents a standard secured to the top of the pump, to which a double-cranked handle m is journaled, as at a. This crankshaft has swiveled to it at 0 p the upper ends of the two rods, one of which passes down through the pump and the other is on the outside thereof and passes through a guideslot (1 in the rim or base 7' of said pump.

- 0 indicates a cap, which is attached to the top of the pump.

Through the top of said cap is provided a slot 3, through which passes the rod d, and a housing If is secured to this top or cap, having a slot u,correspondiug with the slot in the cap and arranged in line and above the same. This housing forms a guideway for a sliding plate 1), which has an opening w, through which said rod also passes. The lower end of the two cylinders aforesaid are provided with removable valve-boxes as or, (shown enlarged in Fig. 4 of the drawings,) which are provided with strainers y y, whereby sediment or gravel is prevented from entering the pump. This valve-box so has an upper and lower collar or flange a 011 its inner side, having central openings b b, and the strainers are bolted to the lower collar by bolts 0' e between said collar and a ring cl, the bolt c serving the double purpose of holding the valve f in place as well as fastening the screen or strainer.

Having thus described the diiferent parts of which my device is composed, I will now ex plain its operation. The operator in drawing water simply grasps the handlezof the crank shaft and revolves it, thus revolvingthe cranks at the same timethe plun gers and theirrods are vertically operated alternately, and by means of the second cylinder caconstant stream of water is supplied to the tubing a, the water passing out of the spout a in the usual manner. The object of the sliding plate, which at all times covers the slot in the cap, is to prevent the water from coming out of the top of the pump. It will thus be seen that I provide a double acting pump which gives great force to the water, and it is easily operated, durable, and at the same time cheap to manufacture.

I am aware thata force-pump has been constructed prior to my invention in which there has been combined two cylinders, two tubes provided with tubes within said cylinders, a valve-controlled receiving-chamber, a tub-e extending upwardly from said chamber, abeam fulcrumed in a support on the upper end of said tube, and detachable rods, one of which is extended above the beam for connection with a wind-wheel, whereby the pump maybe made either double-actin g or single-acting and the opposite sides be operated either by the same power, or one by hand and the other by collar, the bolt 6 of the pair of bolts serving wind-wheel, and I do not claim said consirncthe double purpose of holding the valve in tion herein. place and fastening the screen or strainer,

What I claim is substantially as specified.
